Salmon 2000

from Wikipedia, the free encyclopedia

Salmon 2000 was the name of a project that aimed to bring salmon back to the Rhine by the year 2000 . The follow-up project is Salmon 2020 .

History of the salmon in Germany

Up until about 100 to 200 years ago there were still salmon in all major German rivers, and the Rhine was considered the largest salmon river in Europe. Up to 250,000 animals were caught there in peak years. However, the oft-told story that salmon was a poor man's food is wrong, even in peak years all salmon was sold because it was extremely popular and valuable.

With industrialization and its consequences, water pollution, the straightening of rivers and the expansion of hydropower, the salmon population continued to decline until it died out completely in the 1950s.

Salmon 2000 (Rhine)

Young Atlantic salmon (Salmo salar)

The main trigger for this project was the devastating chemical disaster at Sandoz in 1986, which also convinced the industry of the importance of this prestige object.

Since 1983 the pollution of the Rhine had steadily decreased and the first Irish young salmon were put into the Rhine. In 1986, the Rhine ministers decided on the "Rhine" action program, which also included the Salmon 2000 project.

The International Commission for the Protection of the Rhine (ICPR) coordinated the measures.

The EU made around three million euros available, and the individual neighboring countries made the same amount available again. Sandoz paid € 250,000 into a corresponding fund. Additional funds were also brought in from various sources.

In 1993 the first 14 salmon were caught in the Sieg in North Rhine-Westphalia . The first six salmon in the Upper Rhine were spotted near the Iffezheim barrage in 1995 . The ICPR is assuming a stable wild salmon population in the Rhine area in 2020.

Elbe salmon 2000

The state of Brandenburg launched a similar, ongoing project under the title “Elblachs 2000”. The focus is on the water system of the Elbe tributary Stepenitz in the Prignitz . The Free State of Saxony is also running such a project.

For renaturation , for example, a weir in the Schlatbach was dismantled and replaced by a slat that overcomes a height difference of almost two meters and does not dry out in summer. A basin structure was created with stone bars, which allows the fish to migrate even in summer when the water is low .

In April 1999 the first young salmon were released in the Stepenitz (Brandenburg), some of them with transmitters, so that one can follow their migration to the spawning grounds. Since then around half a million salmon have been released, around 150 have been documented to return to the Stepenitz (as of 2009), and the number is increasing every year. The largest salmon caught was 102 cm long and weighed 8.6 kg.

Saxony bought the first Swedish wild salmon eggs from the Lagan population for rearing in 1994. One year later they were released into the salmon brook system as brooders and since then around a quarter of a million animals have been released every year. The first returning salmon was caught at the Rathmannsdorfer Weir in October 1998 , and this project has also seen salmon returning every year since then. The salmon stream seems to live up to its name, in autumn salmon pits were found here again, which means that the salmon reproduces itself again.

Oker salmon 2000

There are also sustained efforts to reintroduce salmon in the catchment area of ​​the Weser and, moreover, especially in the Aller and Oker area . Since 1994 the stocking of salmon hatchlings has been carried out in the upper reaches of the Oker near Wöltingerode . Under the project name Okerlachs 2000, an amalgamation of fishing clubs, water maintenance associations and other organizations with the support of the states of Lower Saxony and Saxony-Anhalt has been pursuing the project of reintroducing Atlantic salmon and sea trout in Aller, Oker and the backwaters. With the support of the owner of the Wöltingerode monastery, the monastery chamber of Hanover, and other sponsors, a salmon information center was opened in 2011 in the old mill building of the monastery.

Almost the entire area of ​​the Oker between Vienenburg and the confluence with the Aller is equipped with fish ladders through this initiative and the commitment of the State of Lower Saxony ( NLWKN ) or weir systems have been replaced by Sohlgleiten. A fish counting device and information boards have been set up at the fish pass near Meinersen .
